General Information

General Information Comment Organism
metabolism enzyme ascorbate peroxidase 1 (CsAPX1) is involved in ascorbic acid (AsA) metabolism Camellia sinensis
physiological function ascorbate peroxidase 1 regulates ascorbic acid metabolism in fresh-cut leaves of tea plant during postharvest storage under light/dark conditions. CsAPX1 is involved in regulating AsA metabolism through effecting on the changes of AsA accumulation and APX activity in the leaves Camellia sinensis
